## Guides

- [Usability testing MCP](https://hallwaytest.ai/usability-testing-mcp.md): How a usability testing MCP works: your coding agent sends a flow to a real person and reads back the session. All 22 Hallway Test tools.
- [How much does usability testing cost?](https://hallwaytest.ai/learn/usability-testing-cost.md): What goes into the price of a usability test, a formula to estimate yours, and a worked example for testing one flow with five people.
- [How to add an MCP server to Codex: CLI, config.toml and IDE](https://hallwaytest.ai/learn/add-mcp-server-codex.md): Add any MCP server to OpenAI Codex: codex mcp add for local and remote servers, the config.toml keys, project scope, OAuth sign-in and common fixes.
- [How to add MCP servers to Claude Code: commands, scopes, OAuth](https://hallwaytest.ai/learn/add-mcp-server-claude-code.md): Add any MCP server to Claude Code: claude mcp add for HTTP and stdio servers, local, project and user scopes, .mcp.json, OAuth sign-in and common fixes.
- [How to add MCP servers to Cursor: mcp.json, OAuth and CLI](https://hallwaytest.ai/learn/add-mcp-server-cursor.md): Add any MCP server to Cursor: mcp.json entries for remote and local servers, project and global config, OAuth sign-in, the agent mcp CLI and MCP logs.
- [How to audit a mobile app recording with Claude or Cursor](https://hallwaytest.ai/learn/ai-ux-audit-mobile-app-recording.md): Turn a React Native app recording into a prioritized UX audit: your coding agent reads taps, screens, errors and voice and links each finding to the video.
- [How to test a vibe-coded app with real users](https://hallwaytest.ai/learn/test-vibe-coded-app-with-real-users.md): Vibe-coded apps work for the person who prompted them. Five steps to test yours with real users and turn what they struggle with into fixes for your agent.
- [How to test your app with real users](https://hallwaytest.ai/learn/how-to-test-app-with-real-users.md): A complete guide to user testing a web or mobile app: when to test, how many people, where to find them, how to write tasks, run sessions and fix what breaks.
- [Usability testing for AI coding agents](https://hallwaytest.ai/learn/usability-testing-for-ai-coding-agents.md): Coding agents can build a flow and click through it, but they cannot tell where a person gets stuck. How to add a real-user test to the agent loop.
- [What is hallway testing?](https://hallwaytest.ai/learn/hallway-testing.md): Hallway testing is a quick, informal usability test with the next person who walks by. What it catches, how to run one, and how to do it from a coding agent.

## Compare

- [Synthetic users vs real users in usability testing](https://hallwaytest.ai/compare/real-users-vs-synthetic-users.md): Synthetic users are AI personas and agent testers: fast at catching obvious UI mistakes. Real users get confused and give up. When to use each one.

## Alternatives

- [UserTesting alternative for small teams](https://hallwaytest.ai/alternatives/usertesting.md): UserTesting is built for research teams, panels and studies. Hallway Test is one real tester on one flow, sent by your coding agent, $29 per test after launch.
